He sleeps on concrete, doesn't bathe and only eats canned food people donate to him.

Oh, and he may have saved a man's life Monday morning using skills he says he picked up from the post-apocalyptic zombie television show, The Walking Dead.

Kevin Sutton isn't homeless, but has been living in a tent outside the front door of the Best Buy on South Orange Blossom Trail for more than a week to raise awareness of the issue. He plans to stay there until Black Friday.

Sutton, 37, says he isn't out there just to snag a deal on the latest tech-gadget. But knowing the publicity that being first in line can generate, Sutton says he hopes to show people what it's like to live without means in Orange County.

So far, that's meant giving up a shower and time with his family, listening to harsh comments from people judging him as they walk by, and going to bed hungry on the concrete with only a sleeping bag.

"I'm sacrificing as much as I can to be more aware of what's going on in people's lives," he said.

He collects food and other donations for the Love Pantry, which gives meals to families of Orange County children so they don't go hungry when they aren't at school.

At first, he said it was mostly about the charity and getting publicity for his radio show — the Kevin Sutton Show — airing daily on FM 96.9 and iHeartRadio. He does the show by calling in on his cell phone.

But it also has changed his view on the people around him. And he says it's helped him be more aware of how he can help others.

Take Monday morning.

It was just after 11 a.m. and Sutton, who woke up late, was brushing his teeth while talking to his wife on the phone, when he heard shouting.

He said two men were arguing about money when someone started screaming. Sutton ran around his van, which is parked in Best Buy's lot, to see a man bleeding on the ground.

Sutton said he saw a car speeding away and another man running. He said he called 911 and ran to help. He kept the man conscious and found a gunshot wound in his lower abdomen.

A Best Buy employee grabbed a first aid kit and handed Sutton a bottle of water. He cleaned the wound and then used his shirt to apply pressure until emergency medical crews arrived.

"He started shaking and was screaming for his life, 'I'm going to die,'" Sutton said, who sees a lot of first aid rendered on The Walking Dead.

Orange County sheriff's deputies said the man's wounds weren't life-threatening. His name wasn't released.

Spokesman Jeff Williamson said the man's injuries don't seem to be life-threatening. A suspect hasn't yet been found.

Sutton said he didn't hear a gunshot or see the shooter, and he doesn't plan on leaving his spot in line.

The incident did, however, show him how people aren't always willing to help others.

"If that saved his life — me not standing around — that made a difference," he said.
